Install unRAID on your hard drive|
This is still a work in progress
Download Slackware 12.0. Install it on your hard drive.
When the CD boots, login as root. If your drive is not currently partitioned for linux, you need to
run fdisk or cfdisk. If you only have one hard drive currently installed, you can probably run this
without specifying the drive. If you have several drives, you need to specify the drive path, such
as "cfdisk /dev/hda". I like to partition with 100MB for /boot, however large of a swap partition
you want, and the rest on /. Make sure that you change the partition type of your swap to 82, so
setup will recognize it as a swap partition.
Now run setup. Setup your partitions, select reiserfs as the filesystem (you can probably also
choose ext2, but reiserfs is the safer choice for our purposes). When you get to select packages,
this is what you want the initial screen to show:
Base Linux system - checked
Various Applications that do not need X - checked
Program Development (C, C++, Lisp, Perl, etc.) - checked
GNU Emacs - unchecked (optional)
FAQ lists, HOWTO documentation - unchecked (optional)
Linux kernel source - unchecked (we need a newer version, don't bother with this one)
QT and the K Desktop Environment for X - unchecked (unless you want to use this as your desktop)
International language support for KDE - unchecked
System Libraries - checked
Networking (TCP/IP, UUCP, Mail, News) - checked
TeX typesetting software - unchecked (optional)
Tcl/Tk script languages - unchecked (optional)
X Window System - unchecked (unless you want to use this as your desktop)
X Applications - unchecked (unless you want to use this as your desktop)
Games - unchecked (unless you want to use this as your desktop)
Hit OK. You now have the option of fine-tuning the package selection. If you know what you're
doing, choose menu or expert and choose the individual packages. Else choose full. Full will use up
more disk space and install unecessary things, but at least you won't worry about missing something
You need to install developmental tools, and huge-kernel (no need to install smp or
When it's done, it'll ask if you want to create a bootable usb stick. Might be a good thing to do,
but don't overwrite your unRAID stick! I skipped since I don't have an extra usb stick that can be
bootable. On the next screen, select "no modem".
For lilo, choose simple. Next screen, choose the top selection which is standard (otherwise you may
need to edit lilo.conf to choose vga mode to boot the unRAID kernel). Leave the OPTIONAL LILO append
blank, and have it install to the MBR. If you get an error here, you won't be able to boot, so try
to run it again after setup (sometimes I would get an error, but when I tried again at the main setup
menu, it'd work fine, go figure).
Select Yes to configure your network. For hostname, select what you want the hostname to be of your
unRAID server (unRAID's default is Tower, feel free to set it to whatever you want). For domain,
unless you plan on having this on the internet, just put your hostname again. Choose DHCP or static
IP (unRAID's default is DHCP). I chose DHCP. For the DHCP hostname, you can leave that
The next menu is "Confirm Startup Services to Run", feel free to leave it at the defaults. For
hardware clock, generally you want to set it to NO, which is the default. Then you need to
select your timezone.
Now it will ask you if you want to set a root password. Feel free to do so, you'll need one to be
able to ssh in. Now you are done, you can exit setup and reboot (be sure to take out the CD-ROM).
If you were like me and had problems installing LILO, select "Configure" from the main
Need to add: Re-running lilo from setup worked on VMWare but not on Abit AB9 on IDE port.
Configuring manually worked. First mounted /dev/hda3 to /, nano /etc/lilo.conf, ran lilo -v
Another note: Having all kinds of problems just getting Slackware to work on the Abit AB9 Pro.
Cannot boot hard drive off the only ide port, lilo doesn't want to work on the Promise Ultra66, when
I do get it to work the board doesn't want to boot the drive even when it's the first listed, I have
to make sure no other drives are bootable, no bootable cdrom, no bootable usb flash drive, etc. Now
that that's done, the realtek card won't work so I have to have another NIC to continue. Once this
is finished, future users can burn the new kernel files to a cdrom, install, and it should work out
of the box. Edit to above: The Abit ABo Pro works fine now, it did not like the Promise
Ultra66 card. Once removed everything's working normally. Did have to use irqpoll option to old
kernel, no need on new kernel.
You no longer have to compile the kernel, I have prebuilt packages for you. Hopefully we will be able to redistribute the
binaries in unRAID soon, then I can reduce this whole how-to to just installing some packages. If you want to just install
the kernel and modules instead of compiling, then change to the /usr/src directory and download these packages:
If you want to compile any programs, you will also need the kernel-headers package:
Now install the packages:
If you'd rather compile your own kernel, here's the steps to take (otherwise, skip down to **End compile custom
**Begin compile custom kernel**
Goto your /usr/src directory:
Now download the same kernel source that unRAID uses (currently 188.8.131.52 for unRAID 4.3 beta 5 and
You don't need to do anything with the linux-184.108.40.206.tar.gz file unless you're using a kernel source other than what I
provided above. In that case, after unpacking your kernel source to /usr/src and symlinking /usr/src/linux to it (i.e. if
your kernel source is at /usr/src/linux-220.127.116.11, you need to symlink /usr/src/linux to that directory), do this while in
the /usr/src directory:
tar xzf linux-18.104.22.168.tar.gz
Now we've copied over the unRAID drivers and the .config file we need to compile the kernel.
Now we get to compile the kernel!
The next step is now optional, you only need to run make menuconfig if you want to compile in extra
drivers or modules that unRAID doesn't provide out of the box.
Now compile the kernel:
When it's done you'll get the message "Kernel: arch/x86/boot/bzImage is ready (#1)". Copy it and
System.map to /boot:
cp arch/x86/boot/bzImage /boot/vmlinuz-22.214.171.124-unRAID
cp System.map /boot/System.map-126.96.36.199-unRAID
Now you need to make and install the modules:
Ok, we're close now. We need to edit your /etc/lilo.conf file. It's going to vary for each person
but I'll try to help. Edit it in your favorite text editor. Look towards the bottom of the file,
you'll see the current setup. You need to make an exact copy of what's there, except specify a
different kernel. Here's the relevant part in my /etc/lilo.conf:
# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/hde3
label = Linux
# Linux bootable partition config ends
Now we need to add this just below it:
image = /boot/vmlinuz-188.8.131.52-unRAID
root = /dev/hde3
label = unRAID
You've got to substitute /dev/hde3 with whatever it currently is in your lilo.conf file, else that
kernel just won't boot.
**End compile custom kernel**
Now we need to update lilo:
Now we need to download unRAID and copy it to our Slackware install. While in the /usr/src directory download
We need to extract unRAID into its own directory. First make a directory for unRAID, then move the
zip file, then unzip:
mv unRAID* unraid
Now we need to extract the bzroot:
zcat ../bzroot | cpio -i -d -H newc --no-absolute-filenames
Cross your fingers and reboot. Make sure to select the unRAID kernel in the lilo boot. Once we know
it works we'll make the change permanent.
Ok hopefully everything worked fine and you're now running the unRAID kernel. Let's copy over all
the files that are unique to unRAID that aren't in a standard Slackware install. I like to play it
safe, so I go into each directory that needs to be checked and run the cp command from there.
cp -ri * /bin/
cp -ri * /etc/
cp -ri * /lib/
cp -ri * /root/
cp -ri * /sbin/
cp -ri * /usr/
cp -ri * /var/
Ok, now everything's copied over. There's one more tiny thing we need to do. We need to copy over
the bzroot's version of the /etc/passwd file, emhttp freaks out if it sees shadow passwords.
cp -rf /usr/src/unraid/bz-mod/etc/passwd /etc/passwd
If you want to setup User-Shares, you MUST run fuse first. Do so like this:
If you forget and enable User-Shares, then try to run fuse, it won't work (even after stopping and
starting the array). If you accidentally did this, here's how to fix it. Stop the array, disable
User-Shares. Remove the entire /mnt/user directory using the command rm -rf /mnt/user (note
that if you copied anything to a User-Share when it was not working properly, this will completely
delete it, you've been warned!). Start the array. Stop it again and enable User-Shares. Start it
back up, and it should work. You will need to have fuse start up in your rc.local file before emhttp
If this is a new install (you didn't already have a working unRAID setup on this server), you're
ready to start emhttp!
If you have an existing config for this system, we need to copy over some important files from your
usb drive. First we need to mount it. Now if you're just going to use a maximum of two data drives
(and one parity), there's no need to keep the usb drive mounted. You can mount it wherever, or even
just copy over files from another PC (i.e. put your usb key in your windows box and ftp them over to
your new unRAID server). If you have a license, then you HAVE to have the usb drive mounted whenever
emhttp is running. The next steps show you how to do that, then we'll show you where to copy the
Make the /mnt/boot directory:
Edit your /etc/fstab and put this at the bottom (or anywhere really, has to be all on one
/dev/disk/by-label/UNRAID /mnt/boot vfat defaults 0 0
Make sure that the usb drive is inserted, wait 5-10 seconds to make sure it's had enough time to be
configured, then type:
You shouldn't get an error message about the usb drive, do note that this message is perfectly
normal: "mount: devpts already mounted or /dev/pts busy". Now we need to copy everything from the
config directory on your usb drive to your /boot partition. First, you probably have a file named
/boot/config, so we'll need to rename it, then copy the files over.
mv /boot/config /boot/config.bak
cp -rf /mnt/boot/config /boot/
Now you can start up emhttp, and it will read your current config and license key.
(This needs to be further explained) Add the stuff you need to run on every reboot to
Things to look into: Need a more elegant way to do the cp above. Make emhttp auto-start on boot.
If anyone can debug kernel
modules, find out why unraid.o crashes under an smp kernel. Convince WeeboTech that this whole
endeavor only took ten minutes and each time a new unRAID version comes out, it'd only take Tom a
couple minutes max to make this unRAID-max distro.
Ultimate todo: Create Slackware packages so you can simply install a few packages and have unRAID on your system. We can
even create a custom install CD that will install a system with unRAID ready to go. Packages are ready, currently waiting
on permission from Tom to redistribute unRAID.
Some notes (yes I'm probably repeating myself, this is still a work in progress):
If you have a Realtek Gigabit NIC (which is included on the Abit AB9 Pro among many others), it most
won't work after
you've installed Slackware. It
will be recognized and looks like it'd work, but won't (setup will configure it for you, it will say
it's looking for a dhcp server but times out, trust me it's not really working). Once you've
installed the newer kernel AND modules, it will work.
The Abit AB9 Pro motherboard seems to not like the Promise Ultra66 card. When I had a drive
installed, I was able to edit the bios once. Subsequent trips to the bios setup screen would result
in the keyboard not working (tried both usb and ps/2 keyboards). I could clear the CMOS and try
again, it would work for the first edit but not subsequent times. Had other issues with the Promise
Ultra66 card (the one drive I had connected to it was corrupted within a day), so I just chucked
Another issue with the Abit AB9 Pro, related to the JMicron IDE port. After the first boot I'd get
tons of error messages about /dev/hda. Turns out to use the IDE port you need to append the
"irqpoll" option to the kernel. We only need to do this temporarily. When you see the lilo boot
screen (where you select the OS you want to boot), simply type "Linux irqpoll" without quotes, then
enter. You can do this with other kernel options such as noapic. Once the new kernel is installed,
you no longer need that, so no need to edit lilo.conf to permanently add it.
